What data for this category looks like
Financial institutions obtain marketing content data for infrastructure construction projects primarily from project bidding documents, construction logs, completion acceptance reports, on-site inspection records, and customer customized requirement documents. Data update rhythm follows project cycles. Relevant bidding materials are updated after winning a bid. Progress reports are synchronized during the construction phase. Acceptance and settlement documents are added after project completion. Most documents are long-form structured content. They include chapter numbers and professional construction terms. Fields include project number, section division, construction unit, construction period, and budget amount. Units include meters, cubic meters, tons, and other engineering measurement standards.
What constraints these characteristics impose on deployment and upgrade workflows
The long-form structured document characteristics of infrastructure construction marketing content used by financial institutions require longer file parsing timeout settings during deployment. This prevents timeout errors when parsing large tender documents and completion reports. The staged update data pattern requires upgrade workflows to support incremental synchronization. This avoids full re-import and reduces repeated computing resource usage. Multi-source engineering documents include dedicated measurement fields and terms. Deployment requires preconfigured professional term mapping rules to prevent semantic deviation during vector retrieval. Additionally, multi-format input files require the deployment environment to support commonly used engineering document formats such as docx, pdf, and excel.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600-900 seconds | Infrastructure engineering documents are mostly long-form structured content, and standard timeout durations are insufficient for complete parsing |
UPLOAD_FILE_MAX_SIZE | 1000-2000 MB | Large section tender documents and completion settlement reports have large file sizes, so the upload limit must be adjusted to accommodate large files |
Chunk size | 800-1200 characters | Engineering documents contain long sentences and professional terms. Excessively long segments will disrupt term context association, while excessively short segments will reduce retrieval accuracy |
RECALL_TOP_N | Top 8-12 entries | Engineering marketing content has strong professional relevance. Too many retrieved results will introduce irrelevant documents, while too few will miss critical project information |
Incremental Sync Switch | Enabled | Infrastructure project data is updated in stages along with construction phases. Incremental synchronization reduces repeated computing resource consumption |
Professional Term Mapping Rules | Predefined common engineering term library | Engineering terms have dedicated semantics. Predefined mapping rules improve the semantic matching accuracy of vector retrieval |
The parameter values provided on this page are general recommendations that serve as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common errors
- Issue: An
EMFILE: too many open fileserror appears when running thedocker buildcommand. Cause: When parsing large infrastructure engineering files, the number of open file handles inside the container exceeds the default limit, and the container's maximum file handle configuration has not been adjusted. - Issue: After starting the service with
docker compose, the container fails to run normally. Checking logs shows port binding failed. Cause: The platform's default listening port has not been modified, creating a conflict with ports used by other local engineering operation and maintenance tools. - Issue: In an intranet deployment environment, a timeout error occurs when importing large engineering documents. Cause:
PARSE_FILE_TIMEOUT_SECONDShas not been adjusted to a value suitable for long documents. The default timeout duration is insufficient for complete parsing.
How to confirm configurations are properly set
- Upload a single typical engineering tender document, review the parsed segmented content, and confirm the segment length matches the preset configuration.
- Check container runtime logs to confirm there are no errors related to file handle limits or port conflicts.
- Initiate a vector retrieval test to verify that the number of retrieved results matches the configured value.
- Submit staged updated engineering data, confirm that only newly added content is processed synchronously, and that no full recalculation is triggered.
